Un circuit d'attaque tactile est disposé au niveau d'une région de non-affichage d'un écran tactile et s'étend dans une direction parallèle à la direction d'extension de l'électrode d'attaque tactile ; ainsi, la direction d'extension du circuit d'attaque tactile est la même que la direction d'extension de l'électrode d'attaque tactile. En conséquence, chaque électrode d'attaque tactile doit être connectée au circuit d'attaque tactile par un fil d'électrode d'attaque tactile. Afin de réduire la largeur d'une lunette d'un écran tactile capacitif, le fil d'électrode d'attaque tactile est disposé dans une région dans laquelle est situé un circuit d'attaque de grille ; c'est-à-dire que le conducteur d'électrode d'attaque tactile et le circuit d'attaque de grille sont superposés et isolés l'un de l'autre. En conséquence, le fil d'électrode d'attaque tactile n'occupe pas une partie de largeur de la région de non-affichage de l'écran tactile, ce qui permet de réduire une largeur d'une lunette d'un écran tactile capacitif intégré, et de réaliser un écran tactile capacitif ayant une lunette étroite.
